History A 46-year-old woman with known mixed connective tissue disease with clinical features of scleroderma and polymyositis and who was not on specific medications was referred to our institution to assess for interstitial lung disease due to her predisposing condition. She was a nonsmoker, had no respiratory symptoms, and enjoyed good exercise tolerance. She did not have any cutaneous lesions or renal disease. There was no family history of pulmonary or systemic disease. Her routine blood test results revealed a white blood cell count of 4.6 × 109/L (normal range, [4.4-10.1] × 109/L), a hemoglobin level of 7.76 mmol/L (normal range, 7.26-9.18 mmol/L), a platelet count of 189 × 109/L (normal range, [170-380] × 109/L), a bilirubin level of 8 mmol/L (normal range, 1/720), anti-Ro, anti-La, and anti-extractable nuclear antigen antibodies. Chest radiography and CT were performed at presentation and 14-year follow-up. PET/CT was performed at 7- and 13-year follow-up. Throughout this 14-year follow-up period, she remained completely free of respiratory symptoms and continued to go for a brisk walk every day. At 14-year follow-up, there was no substantial change in serum laboratory values, but a lung function test revealed her diffusing capacity for carbon monoxide had decreased to 52%, while her forced vital capacity remained good at 95%; these findings were suggestive of interval development of restrictive lung function.History A 57-year-old man with no remarkable past medical history presented to an outside institution with painless swelling in his right thigh of 6 months duration. He denied any trauma to the site. At that time, physical examination demonstrated swelling in his right upper thigh. All other work-up, including complete blood count and chest radiography, yielded negative results. The initial diagnosis was lymphangioma of the thigh. He continued to experience worsening swelling in his right upper thigh with no other symptoms over the next year. He was referred to our facility, where he underwent US evaluation of the thigh lesion (Fig 1), an MRI scan encompassing the entire extent of his thigh lesion (Fig 2), and a CT scan of his abdomen and pelvis (Fig 3).Health care providers are increasingly providing technologies for patient care; however, patients are still loath to use such technologies consistently. This research examines the impediments to patients' use of e-health portals. Our analysis of 836 data records showed that while privacy and security concerns have a negative impact on attitudes toward e-health portals, increasing the awareness of privacy and security controls alleviates such concerns. Our findings also suggest that individuals worry more about who possesses the right to access their health data (i.e., who, what, when, and why) than the mechanisms used to safeguard data from unauthorized access. We found that perceived benefits and support (i.e., emotional and technical support) positively influenced the determinants of use intentions. The implications of these findings for health care providers and policy makers are discussed.Smartphones have recently become a major target for cybercriminals due to large amounts of sensitive data and credentials being stored on the devices. To protect themselves against cyberthreats, users can employ a range of security behaviors. Although research has largely focused on computer security, relatively little is known about personal smartphone security behavior. The goal of our study was to evaluate determinants of smartphone security behavior based on the combination of the Health Belief Model and Protection Motivation Theory. We extended the models by including the construct of general security orientation. We also developed a smartphone security behavior scale that measured various aspects of this behavior. The sample included 331 Czech Android smartphone users aged between 26 and 81 years who were not IT specialists by employment or education. Path analysis showed that individuals who perceived a potential smartphone security threat as more severe, had higher smartphone self-efficacy, and general orientation and interest in digital security, and less personal experience with a digital security incident reported more secure behavior on their smartphones. Perceived susceptibility to security threats and family and friends' previous experience with digital security incidents did not predict smartphone security behavior. https://www.selleckchem.com/products/eflornithine-hydrochloride-hydrate.html General security orientation affected smartphone security behavior also indirectly through perceived severity. These findings have theoretical implications for the models and also emphasize the importance of general digital security awareness as well as smartphone training to increase smartphone security behavior.When a relationship ends, former partners must make decisions about their online, often public, connections and history, which involve a complex disentangling process. We examined post-breakup behaviors including monitoring, interacting, deleting posts/photos, deleting the former partner, deleting the partner's family/friends, stopping social media (SM) use, and keeping digital possessions. Participants (N?=?256) who had experienced a breakup within the last year completed an online survey. Approximately 38 percent reported experiencing distress over the breakup sometimes or more often. Utilizing latent profile analysis, we identified four latent classes (or profiles) of breakup SM behaviors; we also examined associations between the class and breakup emotional distress. Most participants were clean breakers (61.3 percent), who did zero to very little monitoring, interacting, or deleting and were unlikely to delete their ex-partner, stop use, or keep digital possessions. Wistful reminiscers (12.9 percent) were similar to clean breakers in terms of engaging in very little of any deleting behaviors, stopping use, or keeping digital possessions; however, they engaged in frequent amounts of monitoring their ex-partner as well as interacting with their ex-partner and their ex-partner's family/friends. Ritual cleansers (15.6 percent) were similar to clean breakers in terms of engaging in very little to no monitoring and interacting; however, they engaged in deleting their SM history, their ex-partner's family/friends, and their ex-partner. Impulsives (10.2 percent) engaged in high amounts of all the SM behaviors. In terms of emotional distress, impulsives showed the highest levels of distress, followed by wistful reminiscers, ritual cleansers, and then clean breakers.
